ITR-U 48-Month Window – CBDT Extends Updated Return Time

Notification No. 49/2025, dated 19-05-2025

1. Legislative Update at a Glance

• Finance Act 2025 has amended Section 139 (8A) of the Income-tax Act, 1961, extending the window to furnish an Updated Return (ITR-U) from 24 months to 48 months after the end of the relevant assessment year (AY). The change takes effect 1 April 2025.
• Consequential changes to Section 140B introduce two new slabs of “additional tax” for returns filed in the 3rd and 4th years of the window.
• The Central Board of Direct Taxes (CBDT) has revised Form ITR-U to accommodate the longer window.
